Interconnexions optiques en espace libre dans les calculateurs parallèles SIMD : Spécifications des systèmes complexes

Increasingly complex software requirements often call for the implementation of parallel computation capabilities such as SIMD (single instruction multiple data) systems, which offer high clock speeds but can be penalized by input/output rates. . Optically-connected multi-chip modules (MCMs) provide an attractive solution for producing massively parallel computers with lower interconnection overheads. . Feasibility studies and experiments on free-space optical interconnections reveal that the passband increase achieved by higher connection densities must be traded off against tighter mechanical constraints during system assembly. Some experimental validations have been published, and others are still in progress.
